I have a new 26" Criterion 260 rem barrel with a .160 free bore that I am getting ready to start load development on. The bullets I was looking at are 139 scenar, 140 ELDM, 142 smk, berger 140 hybrid, and berger 140 lrbt. What would you suggest to start with and what has everyone had best luck with in the 140 class? Any other opinions are welcomed that are not listed.I haven't saw much talk on the 140 lrbt's and didn't know if the premium price on either of the Berger's was worth it over the Sierras. Thank you.
